Hi Ben,

Slightly offtopic, but:

Any reason why this is on by default?
I also noticed this while testing IBSS capability some time ago and my 
1st thought was:  "Is something wrong now??"

As the dmesg buffer is circular, all the debug prints start overwriting 
the early bootprints after some time.
When another component fails, it gets difficult fetching a full bootlog 
containing kernel version etc due to this.

It can be turned off easily, but reversing that logic also suggest it 
could be turned on easily should any issues be noticed :)

Thanks,

Koen
